DESTRUCTION REMOVER FOR SINK BRAINS AND THE LIKE Filed June 27, 1934 z v i l( avwemlio'a um M21 Patented Nov. 6, 1934 UNITED STATES DESTRUCTION REMOVER FOR SINK DRAINS AND THE LIKE William F. Schacht, Huntington, Ind.

Application June 27, 1934, Serial No. 732,700

3 Claims.

This invention relates to obstruction removers for flushing drains in sinks, tubs, basins, and the like, the present invention being an improvement upon the spray head disclosed in the application 5- of Clifford A. Schacht, Serial No. 615,439, filed June 4, 1932; and one object of the invention is'to provide a hollow head having a resilient bumper ring positioned thereon to prevent the material of the head (usually metal) from coming into direct contact with the surface of the sink, tub, orthe like; said ring projecting beyond the open face of the head so that in event the drain should become obstructed with grease, sediment, or the like, the head may be placed over the drain and when water is forced through the head a tight connection will be formed by the ring between the head and drain so that water will be forced under pressure into the drain to clear same of any obstruction.

In the aforesaid co-pending application the bumper ring was applied to a: spray head having a perforated spray face, but I have found that in a perforated spray face the openings for the water are not sufficiently large to create the necessary water pressure required for properly clearing the drain of obstructions; and I have also found that if the spray face of the head is omitted entirely the thin metal of the head will Warp and bend under ordinary use so that the same soon becomes useless.

The principal object of my invention is to provide a spray head having a resilient sealing and bumper ring, and having an unperforated plate instead of the usual perforated spray plate closing the open face of the head, my plate reinforcing the head to prevent warping and bending of the head, and having a single central opening of substantial cross-sectional area whereby when in use a much greater force or pressure of Water 'wi1l be transmitted by the head into the drain for removing obstructions. When the hose of the head is attached to a water faucet and the head held down over the drain of the sink, a stream of water under pressure will be forced directly into the drain to clear the drain of sediment, grease, or the like, and since the rubber bumper ring protrudes beyond the face of the plate a vacuum will be set up between the head and drain so that very little exertion is required to hold the head in place on the sink even though the full pressure of the water is used, and no water will escape between the sink and the bumper ring.

A further object is to provide a head in which the rubber bumper ring is formed with a wide flat outer end so that same'will cover a large surface of the sink, thereby creating a greater vacuum between the head and sink.

I will explain the invention with reference to the accompanying drawing which illustrates several practical embodiments thereof, to enable others to adopt and use the same; and will summarize in the claims the novelfeatures of construction, and novel combinations of parts, for which protection is desired.

In said drawing:

Fig. 1 is an elevation of my obstruction remover applied to a sink drain showinginsection the resilient bumper ring, and showing partly in section the reinforcing plate. I

Fig. 2 is a bottom plan view of the remover.

Fig. 3 is an elevation of the head, showing in section a modified form of'ring. v

As shownin Fig.1, the head 1 is of form similar to the usual spray head, having its upper end contracted to form a nipple 2 for the reception of the rubber hose 8 for attachment to a faucet (not shown) adjacent the sink S. The open or outer end of head 1 is materially widened, and adjacent the outer end is a short cylindrical portion 4 terminating in an annular flange 5 at its outer end extending around the head.

In place of the usual spray plate I provide a strengthening or reinforcing plate 6 consisting of a disk having an annular peripheral flange 7 adapted to fit over the flange 5 of the head and to be rolled down over the flange 5 to interlock the flanges 5 and 7 and securely hold the plate 6 to the head 1. In the center of plate 2 is an opening 8, of somewhat larger diameter than that of the nipple 2, through which the water in the head is discharged upon entering drain D of the sink, the relatively large opening 8 permitting the water to pass with sufficient volume and pressure to remove obstructions in the drain pipe D.

The plate 6 on the outer end of head 1 having the central opening 8 will reinforce the head, and the single large opening 8 permits a maximum pressure to be set up for flushing the sink drain D. The head 1 and plate 6 are preferably stamped out of thin metal and the parts set into a press and the flange 7 curled over the flange 5, and the bumper ring 9 is then placed over the curled flange '7.

The bumper ring 9 preferably comprises an annular rubber band of substantially rectangular cross-section, the bottom face 9a of the ring being founded as shown in Figs. 1 and 2, while the outer wall of the ring is preferably rounded as at 9b adjacent the inner end of the ring. Within the inner wall of the ring 1 is an annular groove 9d for receiving the annular rolled flange 7 of the plate 6 whereby the ring 9 will be securely locked on the head, with the inner wall of the ring fitting snugly around the cylindrical portion 4 of the head. The ring 9 will be made somewhat smaller in diameter than that of the portion 4 so that the ring must be slightly stretched in mounting same thereon, and the resiliency of the rubber and the engagement of the flange '7 in the groove 9d securely locks the ring in 'place."

The lower rounded face 90 of the ring protrudes below theflange 7 whereby the head may be placed upon a flat surface'such as a sink S with out any metal part of the head touching such surface.

The rubber ring 9 acts as a bumper or a protector and prevents the metal parts of the head 1 from coming into direct contact with enamel sinks, bath tubs and the like, as the lower end of the ring 9 protrudes below the metal of the head. The ring 9 has sufiicient contact surface on the portion 4 to prevent leakage of water therepast. When the hose 3 is attached to the faucet, and the water turned on, the head may be held down over the drain D to permit water to be forced down through the opening 8. of plate 6 into the drain pipeto free same from sediment, grease and the like. As'the ring 9 extends beyondthe face of the head 1,a suction is created sufficient to hold the head in place even though the full pressure of the'water in the main be used. The plate. 6 not only reinforces the head 1 but by reasonof the single large opening 8, it provides a greater pressure for cleaning out the drain.

In Fig. 3 a modification is shown in which the rubber ring 10 is substantially rectangular in inner wall; The ring 10 is considerably wider than the ring 9 of Figs. 1 and. 2, and has a much wider outer face 10a which is formed flat instead of rounded. This form of ring will have a greater contacting surface with the sink S, and hence a greater vacuum may be built up under the head while in use.

I claim:- 1

1. In combination with'a head having an open face and having an annular exterior rib adjacent the open face, a plate across the open face of the 1 head having one or more relatively large openings substantially axially disposed therein, and aresilient bumper ring of substantially rectangular cross-section stretched around the rib making a tight contact therewith, the ring protruding beyond the plate face; and the inner wall of the ring contacting with the head.

2. In combination with a head having an open face and having an annular exterior rib adjacent the open face, a plate across the open face of the head having an annular flange rolled over the rib and having one or more relatively large openings substantially axially disposed therein; and a resilient bumper ring of substantially rectangular cross-section stretched around the rolled flange and making a tight contact therewith, the ring protruding beyond the plate; and the inner wall of the ring contacting with the head adjacent the rib. I

3. In a combination as set forth in claim 2, said ring having an annular groove in its inner periphery for the reception of the rolled flange, the outer end of the ring being relatively wide and flat for contacting with the surface of a sink or 1.19 the like to eifect a seal between the head and surface.
